單數(shù)，he with his parents中的with his parents為伴隨狀語，實(shí)際主語為he，故謂語動(dòng)詞用單數(shù)。例句：He with his parents goes to Shanghai once a year.

伴隨狀語是指狀語的動(dòng)作伴隨主句發(fā)生，它的特點(diǎn)是：它所表達(dá)的動(dòng)作或狀態(tài)是伴隨著句子謂語動(dòng)詞的動(dòng)作而發(fā)生或存在的。伴隨狀語的邏輯主語一般情況下必須是全句的主語，伴隨狀語與謂語動(dòng)詞所表示的動(dòng)作或狀態(tài)是同時(shí)發(fā)生的。

由“with+賓語+賓語補(bǔ)足語”構(gòu)成的復(fù)合結(jié)構(gòu)，在句中可作狀語，表示伴隨。這一結(jié)構(gòu)中的賓語補(bǔ)足語可由現(xiàn)在分詞、過去分詞、形容詞、副詞或介詞短語等來充當(dāng)。例如：

1．With production up by 60%, the company has had another excellent year.

產(chǎn)量增漲了60%，公司又是一個(gè)盈利年。

2．He soon fell asleep with the candle still burning.

蠟燭還亮著，他很快就睡著了。

3．She sat there alone with her eyes filled with tears.

她獨(dú)自一人坐在那兒，眼里充滿了淚水。
